The Lantern for Suffering
Humanity. — A NEW SCHEME, —
WE are about to suggest a new method whereby many of those who are, from various causes, cut off to a certain extent for a time from the outer world, may have their burdens lightened. We refer to convalescent patients in hospitals.
The intended plan is to give the patients an - occasional pleasant evening in the form of a lantern entertainment. Imagine the pleasure. with which a person will welcome this exhibition who may have, for a long time, been laid up on a bed of sickness, owing to disease or accident, to ! which all are liable.
it is proposed that two or three complete lantern outfits be obtained, exclusively for the use of metropolitan hospitals, in which exhibi- tions could be given at frequent intervals.
We feel assured that there is sufficient liberality and kindly feeling among manufacturers to con- tribute apparatus for this purpose, which could be placed in the hands of trustees ; and we feel equally assured that among the large body of lantern exhibitors many would be only too glad to devote an evening, and conduct an occasional '
exhibition. It would also be a chance for young exhibitors acquiring experience in the conducting of exhibitions before larger and perhaps more critical audiences.
considerable number ofslides would be required: in order to give diversity to these entertainments ;. but after once started, we have no doubt that many of our readers would be very pleased to donate two or three slides for such a praiseworthy object.
The selection, of course, would be left with the donors, but some suited for the amusement of children should be included.
We hope to have an immediate expression of
opinion from our readers, and to be able to announce in next issue that action has been taken in the matter.
Letters addressed to the Editor of this paper, at Dorset Works, Salisbury-square, London, E.C.,. will be promptly acknowledged.

Oil Lamps.
A CORRESPONDENT details a somewhat strange
behaviour of a lamp of the Sciopticon class. In
| the course of his letter he says :—' About two. | years ago I bought a pair of lanterns. I first tried
Alexandra mineral oil, but found that would not do at all, for when the oil got hot, the flame would rise ; turning down the wick had no effect,
the flames came out of the top of the chimney..
Then I tried common American petroleum, but
could not get a light as bright as I should wish. |The lamps have four wicks.’”’ He further asks the
name of a good oil. The manufacturer trom whom the outfit was
purchased, in a recent interview suggested that the:
wick must have been first turned above the burner
,and then lighted. Under those circumstances.
the flame would shortly rise, and turning down would make matters worse; but as our corres-
pondent says he has had his lanterns about two- i years, it is to besupposed that he is conversant with
the manner of obtaining a light. He mentions
that a different oil gave better results. Thinking:
that perhaps the flashing point of the oil might
be too low, we communicated with Messrs. James. L. Thomas and Co., of Exeter, who are agents.
for the oil mentioned. They say—' The burner
‘itself appears to be the only cause of the defect. We have had experience ourselves of this pattern,. and very unsatisfactory it is ; it is impossible to-
obtain a good light with the burner, from the very nature of its construction, with any oil. Many of our friends have superseded this burner
altogether, and when the change has been effected,.
«Alexandra oil has answered perfectly. As to the

merits of Alexandra, this oil possesses every Con- stituent of success for this work. It possesses a
flashing point as high as from 135 deg. to 140 deg. | Fahr., the light is perfectly fine and steady, but
it requires a perfect form of burner to derive these advantages.”
To obtain a satisfactory light with even the best forms of burner, the lamp must be kept in good order. Some time ago we published instruc- tions respecting the care of oil lamps.
The care of a lamp appears such an every-day matter that many seem to think it should under any and all conditions give a good light.
Messrs. Perken, decided in future to send out instructions with each of their oil lanterns. These being concise, we here reproduce them :—
(1) Wipe the front and condensing lenses with a piece of soft silk free from every particle of dust.
(2) Thoroughly dry new wick before putting into the lamp, let the wick be saturated with oi] before lighting.
(3) The best parafiin oil gives the brightest light. Diener’s At safety oil, and Strange’s A r crystal oil, also the Vaseline Co.’s Luxor, are specially recommended.
(4) The best quality wick is indispensable to brilliant illumination, Cheap wicks and cheap oils are false economies, answerable for very many failures and disappointments when exhibiting the lantern. (A large and strong pair of scissors should be used to trim the wicks, or preferably the “ Optimus " patent wick trimmer, as a perfectly straight
and even edge to the cotton is necessary to the avoidance ; Cut off the protruding |
of an uneven flame and smoke. corners to allow the flame to draw evenly upwards.
(5) Light the lamp with wax vestas or tapers. The heads
of matches or charred paper are liable to fall into the air passages between the wick tubes, so impeding complete com- bustion,. _ (6) When lighting the lamp, do not turn the wicks high immediately, but raise them little by little at intervals of a few minutes. This system, besides improving the flame, gradually warms the condensing and front lenses ; if suddenly heated they are likely to crack, Cold air being allowed to blow ona heated condenser will also certainly cause unequal contraction, a cracked glass.
(7) The oil reservoir and other exterior parts of the lamp should be wiped perfectly dry, otherwise the oil about them will vapourise and fill the apartment with a most unpleasant odour.
(8) The wick should be trimmed prior to each exhibition, and when not burning should be turned one-eighth of an
meated with oil.
(9) A plentiful supply of pure airis an imperative necessity to perfect combustion or perfect illumination, In crowded rooms, opening a window or door will greatly improve the
light of the lamp ; insufficiency of air ensures a bad light and |
an unsatisfactory exhibition. Like ourselves, the lamp gives its best results when it enjoys pure air, clean surroundings, and pure food (oil). : :
A new oil lamp for lanterns has been invented by Mr. William Stocks, of Rye. It is claimed by the inventor that it will burn with great steadiness of flame, combined with intense brilliancy, and there is an arrangement whereby, it is said, it can be successfully used in a room in which the air is somewhat vitiated.

{THis popular camera—of which we here give a
description—is the invention of Messrs. Swinden and Earp, of 21, Islington, Liverpool, who were awarded
‘the medal for its excellency at the exhibition held Son, and Rayment have |
last year in connection with the Photographic Society of Great Britain.
‘The camera, which, like many hand cameras, has the appearance of a box, covered in black leather, is devoid of projecting handles or knobs. The }-plate size measures 1osin. long x 5fin. wide < din.
deep.
The movements for exposing and changing the plates are operated from underneath. A door at the back of the camera opens by pulling up a small ring at the end (Fig. 1), and it is here that the > apparatus is charged with plates
The plates, previous to being placed in the camera, are backed with orange-coloured paper: this. is speedily effected with the aid of a special tool supplied with each outfit. The compartment for the stock of plates is capable of holding twenty ; into this they are placed in an upright position, after which a follower (C) is placed against the last plate.
In order to insure the plates being kept against the exposing plane there are two spring rods (AA), which during the time the camera is being charged are turned on the sides at BB. When placing the
Fie. 1.
follower (C) in position it engages with a rod (1*), and moves on a ig. 2), from
which terminates in a pointer, graduated scale under the camera at M (F which the number
in the may be at a
remaining chamber ascertained glance.
On the top of the camera is a sunk
of which is a scale ; along this an arm Fie. 2. moves, so that the lens may be set to any desired focus. The front containing the lens is racked to and fro by turning H until the arm arrives at the required figure on the scale.
The shutter, which is of the Kershaw pattern, I> secured to a hinged door, and works in front of the lens. It is operated by a simple arrangement ; by

pulling the cord J the shutter is set, whilst a touch on | cord K makes the exposure.
When it is required to insert a stop in the lens, or alter the speed of the shutter, the front may be opened, as shown in Fig. 3.
The method of changing the plates is as ingenious as it is novel. At G (Fig. 2), underneath the camera, | is a bolt; when this is pushed up it causes two pro- |
jections or teeth to raise the ex- ‘ - posed plate clear of the bar which | mee previously kept it in position ; the | bolt is then pulled slightly down- ; wards, and causes a projection to | . press on the upper edge of the | plate, which liberates it from the groove above, causing it to be! deposited face downwards in the receiving chamber, from whence it is taken for development. ae The RR lens is manufactured Fic, 3. by Laverne, which is a guarantee of its high class qualifications.
Should it be wished to take a view on a vertical plate, those that have been exposed and passed into the receiving chamber are secured in position by turning a small brass arm, placed at the side of the lens, as shown in Fig. 3.
For time exposures the camera can be placed on an ordinary tripod, anda cap used. Asa precaution when Opening the front of the camera, the flat catch L (Fig. 2) should be turned down, which causes a shutter situated behind the lens to close, thus preventing access of any light.
The camera is carefully and cleverly made, as well as beautifully finished; and after one has mentally grasped its mechanism it will be found to work with ease and nicety.
Two firms of plate manufacturers—viz., Messrs. ' Mawson & Swan, and R. W. Thomas & Co., Limited— ' supply plates ready backed specially for these cameras,
‘so that every facility is put in the way of the users.

Hints on Enlarging. By A. R. DRESSER.
CHAPTER II. |
AS I stated in my previous paper, there is much more trouble and expense in making an enlarged negative than by enlarging in bromide direct ; but there are | some advantages, such as combination printing, as | you can take certain parts out of any negative and make two or three positives as required, then bind them together and copy with a wide angle lens, and the negative thus obtained will be in focus. When one can work by daylight it is far the best to do so; but for those unable to find time for so doing a good way to work is by using your magic lantern; nowadays almost every amateur {f
Positive in frame G (Fig. 1), and then about 6ft. or 7ft. away from the negatives, place your lantern, fake out the lens, and only use the condenser ; then move lantern back and forwards until the disc of light is about 3ft. in diameter ; then place so that the nega- tive is in the centre of the disc of the light thrown by the lantern. Mind and put a piece of ground glass behind the negative, or else you will not get even illumination.
If you do not possess a magic lantern, focus by a lamp, and use magnesium wire for the exposure, and by a few trials one will readily ascertain the necessary exposure.
In my previous article I described my apparatus, and gave a rough drawing. Now in Figs. 2 and 3 I give different drawings of it—viz., camera as ready
for enlarging up to 8x 10 (Fig. 2). You see the part used for holding the negative is slightly different, as I have arranged the holder for the negative so that it can be moved to any angle; this I find of great use when
| copying a negative that has not got the lines straight.
It will be observed that the general principle of Figs. 1 and 2 is the same; but the support of the camera—viz., AA—is not supplied with legs, but can be moved about and put on anv table or stand ; then the front (E) for holding negatives is quite different, as the
2
: part that holds the negative works round in a circle, so
that you can place your negative vertical, horizontal, or at azy angle with ease. The drawing (Fig. 4) will explain what I mean. Take a piece of wood, say
' rqin. square (A), and with a lock saw cut out a circle
about gin. in diameter (J3); then cut two pieces of sheet tin the same sizeas the wood—viz., 14in. square— and cut out a circular hole of about Sin. ; now place a piece of tin each side of the wood, and screw it on wood, and then you will find the circle of wood (B)
has, or ought to have, one. The best way to use the lantern is, of course, with the limelight, and as I always use that light, I will describe the way I work, taking it for granted the limelight is used. Place your negative or

GENTLEMEN,—In reference to the pair of Lan- JON, tern Lenses you made specially for me, in working ba ts RN, I found the illumination perfect; the definition aHiGH HOLENDON. and crispness of the iiss left nothing to he
desired. I also found an immense depth of focus, which is a great desideratum, as it saves the trouble of continually having to focus every slide (owing to the different thickness of the glass used in the slides). This is a very important feature. It is a class of lens that I have long felt the want of, and which at last you have been able to realise. I must not overlook the fact of their being symmetrical in form and free from distortion. I need only mention several gentlemen of eminence in the art-science of Photography who fully share my opinion, viz., Messrs. H. P. Ropinson, VALENTINE BLANCHARD, Frank M. Goon, and many others who were with me on several occasions in the gallery when working, and in addition I need only refer you to the London daily press and other papers who speak in very high terms of their performance. The mounting and finish of the lenses leave nothing to be desired, and in my opinion the lenses are absolutely perfect.

(B) ; nail it down tight, and saw out the wood so that ! the negative used gets all exposed, and you havea:

This carrier can be made altogether in wood, if desired; but I have given the instructions for making it at the minimum of expense. The enlarging stand, as explained, with the front, is now on the market—by the Fry Manufacturing Company—and is sold as “ The Dresser Enlarging and Reducing Apparatus.”
If you refer back to Fig. 2, the camera which I use for enlarging, you will see it is for enlarging up to § x 10 only ; but by taking out the ground glass back (H) I can place the front of an extending camera in it and enlarge up to 15x12. -Fig. 3 shows the camera with extension on it, as used for enlarging up to this size ; the length of focus of this camera is 6ft. 6in., and I can enlarge a }-plate up to 15 x 12, when using a Beck R.R. for 8x 10 camera. The drawings will, however, explain what I mean. I have just had the camera and stand made to my drawings, and the cost of allwas £11 or £12; and anyone who wants to go in extensively for enlarging cannot do better than in- dulge in one, if he can find time to work by daylight ; but I do not recommend it for artificial light.

The Photography of Microscopic Objects.:

of division, and consequently better able to render minute detail), one or two developing dishes, and a ruby lantern, in addition to the microscope—which of course every microscopist has —is all that is needed. The microscope in use is to be placed horizontally, and is therefore in the same position as if the camera lucida were being used, the mirror being removed or turned aside, as it will not be required. The lamp— which is the ordinary small micro-lamp—must be placed with the wick turned edgeways, and care must
be taken that the flame is exactly in the optical axis of
the microscope. I find that if a small piece of camphor, say about the size of a hazel nut, is putin the lamp
; with the paraffin, in which it readily dissolves, it will
most decidedly increase the whiteness and luminosity of the flame. The bull’s-eye condenser inust be placed between the lamp and the microscope in such a position as will best illuminate the field.
Many workers remove the eye-piece from the micro- scope. I prefer to leave it in its normal position, for the following reasons :—First, because it enables a
! good magnification to be obtained with a camera of ordinary
length; and secondly, because whilst
. focussing the image on the ground glass I can reach
| to arrange any special apparatus for so doing.
all the adjustments of the microscope without having Iam aware that by the use of the eye-piece a certain amount
| of light is lost, but that is of little consequence in
using the low powers. For instance, with a 2-in. objective a fully exposed negative may be obtained in from ten to twenty seconds, the object being say a fairly transparent section of wood, an exposure which no one could object to on account of its length.
The camera must be rigidly fixed, and placed so that the eye-piece of the microscope will pass through the centre of the hole in its front, in place of the ordi- nary photographic lens. Of course the junction be- tween the microscope and camera must be made light-tight, but that is easily effected by wrapping a strip of velvet round the microscope tube until it fits in the camera front. It isadvisable that a rough base board be made for the camera, which should project in front far enough to enable the ‘microscope and lamp to stand upon it, as by this means the whole apparatus is made much more rigid, which is a very essential point, as the slightest vibration or shifting will spoil the plate. ;
The focussing screen next claims our attention, and my method, which is a modification of Mr. J. B. Dancer’s, I will now describe. The ground-glass of the finest description is to be slightly warmed, and a piece of wax rubbed all over it. This will consider- ably increase the transparency and fineness of the grain’ Now draw two pencil lines diagonally across it
on the ground side, and in the centre, where the lines
bably is when working with high powers, and diatoms, | test objects, and such subjects are photographed; but if : the low or medium powers of the microscope are used, . ; taining a sharp image, but to make it still more cer-
the microscopist will find it very simple, and with very little practice will be able to obtain tolerably good negatives, from which it will be an easy matter to pro- duce effective lantern slides
The apparatus absolutely required is very little. An ordinary j-plate camera without a lens or stand, a few chemicals, a packet of dry plates (preferably a slow brand, as the silver bromide is in a much finer state
cross, Cement a cover glass with Canada balsam. This entirely destroys the grain and produces a transparent circle. There ought to be now little difficulty in ob-
tain it is advisable to use a focussing glass. I use for this purpose a D eye-piece, with the eye-glass removed. and the cap made of such a length that when’ it is resting on the f/vz” side of the ground glass the pencil lines are sharply in focus. If now the focussing eye-piece is placed over the transparent centre of the screen, and the microscope adjusted until the object
C4 The Opticel Magic Lantern Jou
placed on its stage is seen sharply defined, it follows that the sharpest image is in the same plane as the | surface of the ground-glass. When the focus is ob. _ tained the focussing screen must be removed, and the sensitive plate placed in its stead.
It will be as well to mention that the actinic and visual foci of microscopic objectives do not of necessity lie in the same plane, in fact as a rule the actinic
focus is slightly beyond the visual. In the low powers ; this difference is sometimes considerable, and in the .
high powers so small that it may beentirely neglected.
In consequence of this over correction of the objective, |
on developing the plate, the image, which was accu- rately in visual focus. will be slightly indistinct, but as this error is constant, it may be very easily corrected in the following manner. Place on the stage of the microscope an object having a slight thickness, and focus accurately any part of it, preferably near the centre. Expose and develop a plate, and in so doing be very carefi/ not to alter the adjustments of the microscope or to shift the object on its stage. Now carefully examine the negative and note the part which is in sharpest focus, then having replaced the focussing screen, rotate the milled head of the fine adjustment until the sharpest part of the image seen corresponds with that of the negative. Makea careful note of the amount of rotation required to effect this, as this will be the correction that must always be made | (with the objective in use) after focussing, and of course before exposing. With many objectives no correction is required.
If the negatives are for making lantern slides from I would advise that the exposure be very full, so as to obtain a negative soft and full of detail.
Use the /owest power objective that will give the ne€cessary detail, and enlarge the resulting negative if necessary.
One other point in conclusion—test screen and double back. and make quite sure that the ground glass and the sensitive plate are exactly In the same plane when in the camera. This is most important in micro work. *

Tr South London Photographic Society held an exhibi- tion (members’ work), lantern entertainment and concert at Manover Hall, Peckham Rye, on the evenings of the 21st and 22nd ult. A fine display of work was exhibited. The judges, Messrs. Dresser, Trail] Taylor, and Warnerke, awarded the prizes as follows :—(A) Best general work, Mr. Rice, silver medal; Mr. Kkirby, bronze medal. (8B) Six best pictures taken at society's excursions, Mr. Kelly, silver medal: Mr. Farmer, bronze medal. (c) Best six local views, Mr. Webb, bronze medal. Inclass p, hest series of lantern slides, the merits were as follows: first, Mr. Rice; second, Mr. Farmer ; third, Mr. Boydell ; but it having been previously arranged that an exhibitor taking one medal was disqualified for taking another, and as Messts. Rice and Farmer had alreacly won them in Classes A and B respectively, the bronze medal was awarded to Mr. Boydell. The hall was well filled by an appreciative audience. Mr. Banks placed his fine triple lantern at the service of the society, and, with the assistance of Mr, Gardner, operated the instrument. Besides pictures, some apparatus was exhibited, including the 12 by 10 camera which the society lends to its members ; Mr. Howell had a stand of general apparatus ; and Mr. Slater, of South- ampton-street, Camberwell, exhibited a quantity of styles of frames and mounts.

By ALBERT TRANTER.
BEING the possessor of one of those entertaining , instruments, a standard size optical lantern, I recently | purchased a set of 3}in. chromo-litho slides to use with it,and since their purchase the thought has struck me that pictures for the lantern could be so produced in a superior style if they were printed on glass coated ‘with albumen, in the same way as the glass plates are prepared to produce those beautiful albumen lantern photographs. ‘The advantage to be so obtained lying in the albumen presenting a somewhat absorbent character compared with the surface of the mere glass, and thereby allowing the outlines of the pictures to be presented in a less blurred or rough manner, sharp- ‘ness or clearness of outline being such an important Consideration when one’s credit as even an amateur lanternist is at stake. If such slides were carefully prepared, | think that for itlustrating subjects that are most likely to be wanted to be illustrated by the owner of a three or four wick lantern, they would answer most requirements of such a lanternist.
Of course for producing views of natural scenery, such pictures will never come up to photographs, with all the details and lights and shadows which they give so accurately ; though to properly show those the ; lime or electric light is required.

Since writing the above { have read the interesting item in the November issue -of this journal by Mr. Arthur E. Morton, reprinting on gelatine films by aid of the typewriter, and the thought has occurred to me that the same mode of printing, as regards the ; medium for receiving the impressions, could be adopted in producing the coloured chromo litho slides above mentioned, as I should think such or a ; similar surface to that described by Mr. Morton would be admirably adapted for receiving impressions made in producing such pictures ; the pictures afterwards receiving a coat of varnish to perfect their transparency before being placed between the two glasses. And I do not see why slides prepared in such a way could not be soldat the rate of, say, 3s.6d. per doz., for instead of printing on paper, and then having to go to the trouble of transferring them toglass, it would only be necessary to print at once on the gelatine films, and then varnish and mount same; instead of the tedious process of of having to use several sorts of varnish, and exercising no little care in removing the paper on which the pictures are printed.

Flashes on Lantern Topics, By BULL'S-EYE.
THE Edinburgh Photographic Society’s International Exhibition was opened just fourteen years after their first one, on November 14, and in the same place—the Royal Scottish Academy National Galleries—and is a great success. There are at least two thousand exhibits, which range in interest from the earliest Talbotype (a view of Laycock Abbey), the earliest Daguerrotypes and cameras, down to the latest triumphs in apparatus and photographs by the latest and every known process, which in many instances are of rare excellence.
There are not many varieties of lanterns exhibited—indeed the collection is most meagre—but among them must be noted as

In the coming lantern season there will crop up the usual number of complaints of lack of light in the lamp ; and allthe old and some of the new causes were suggested in the case of a friend of mine, who was quite up to managing his Sciopticon, but who failed to get a decent light, and has had to fall back upon a mutual friend, from whom he borrowed, and left his After trying everything the oil was changed, and the light proved perfect. Here the oil which would not light up was taken from a new barrel of the best for household pur- poses, and for the ordinary lamps did its purpose, but was not suited for the lantern. In the same connec- tion one of the managers of our extensive vil refineries gave his advice, which was to the effect never to use over-rectified oil, the whole body being taken out of it ; and what was wanted for enlarging lantern purposes was a good solid flame—as he expressed it; one with a body in it ; and the commoner Scotch oils were the : best for the purpose.

A Light Folding Tent,
By Axbrew C. COoLe.
ON looking over some of the back numbers of this Journal, I observe severa) parties have been giving particulars of how they extemporized dark rooms.
Most of my negatives and lantern trarfsparencies have been developed in the evenings, and I have used my dining room for the purpose, merely turning out the gas and placing a ruby lamp upon the table. This answered capitally so long as the work was carried on alter dark; but I have. for daylight pur- poses, constructed a compact folding tent. This | find particularly handy for purposes of re-charging my hand camera, and inthe hope that it may be of benefit to my fellow workers I give particulars, so that anyone with a little mechanical skill may be enabled to make One at small cost.
Procure twenty-eight running feet of planed deal, tkin. < Jin.,and saw it up in lengths of the following sizes :—lwo pieces 24in. long; two Pieces 22In. long ; two pieces 20in. long ; eleven pieces 18in. long.
With the aid of glue anda few small nails make four’frames of the following dimensions, allowing the corners to overlap, thickness, so as to make ‘the pieces lie flush :—24in. * by 18in., 22in. x 48in., 20in. X18, 18in. * 18in. There will still be one 1Sin. length®left ; this should be secured across the centre of the largest frame.
With screws fasten a piece of wood, r8in. x 2in. x ain.,at say the right hand side edge frame at an angle slightly inclined towards the frame
Now take the frame 2oin. the largest frame, leaving a distance of din. of one end of the lower frame exposed, and with small brass hinges connect them together. When this upper frame is raised on its hinges it will be found that its thickness will just fill up the gin. space that was left at the end of the lower frame.
Next the 22in. x 18in. frame is in like manner hinged to the small zin. upright at end of the largest

frame, so that it may be folded over ; then in turn the smallest frame E is hinged to this. so that it can fold ‘under. Fig. 1 shows the framework open, and Fig. 2 closed. A couple of brass strips forming a hook can be secured from D and C to A, which will make the frame sufficiently rigid.
So much for the frame; now for the covering. Mine is covered with a fabric sold at most photo- graphic dealers, consisting of one thickness of ruby j coloured glazed lining, with a thickness of canary coloured twill on the outside. This I tacked round the bottom frame, commencing at the left hand side, and continued it up to the end of D, leaving just a little fulness at the hinge of B.
After bringing the fabric over E and C, the end should be tacked at the part of A from which the other end started. After the piece for the back is cut ‘out it should be sewed to the edge of the material | which surrounds the frame. In like manner a loose | piece is secured to the front, but this should be so fashioned that the mouth may be tied around one’s waist, the head, shoulders, and arms being inside the tent. | The tent may be set on a table near a window, and will be found very handy for either developing or changing slides, and when not in use may be folded up in small compass, space being allowed between E. and C for the folding in of the loose fabric. ,
If the material is put on tolerably tight a small strip i fastened on C is quite sufficient to keep E in position.

The | rotation of the top, during the attempts at spinning, causes an electric current, doubtless much to the sur- prise of the party trying to spin it.

YACHTING STUDIES.— Messrs. G. West and Son, of Southsea, who have acquired a reputation for their fine photographs of yachting studies, have added the making of lantern slides from their negatives to their business. This firm have sent us a few interesting slides of yachts under fullsail. We recently projected them, ata public exhibition, on a r6ft. screen, and they fairly ‘brought aown the house.”
METAL SLIDE BrnDERS.—A binder and mat in one has been devised by Mr. Moore, of Birmingham. The binder, which is first coated with a cement, is bent over the edges of the slide, then rubbed smooth with a special tool for the purpose. One unaccustomed to this style of binding slides requires some practice before becoming proficient; but after this has been attained slides can be quickly and well bound in a short spacc of time. lasting wear, and look very neat.
CATALOGUE.—The eighth edition of the catalogue of Messrs. Theobald and Co., Kensington, is to hand. In it we find descriptions of all kinds of lantern appara- tus, from the toy lantern to the high-class scientific instruments. We observe that this firm have a specially-prepared oil, for which they claim a large percentage in the increase of light compared with ordinary kerosene. Messrs. Theobald and Co. have also an interchangeable jet, which can, by the move- ment of a lever, be converted into either a mixed or blow-through jet. A strong feature with this firm is the manufacture of coloured lithographic slides, of which they have a very large variety. We notice that they have in this manner illustrated Stanley’s tour through Africa, a set which has been, and is, in excep- tional demand. Besides supplying goods wholesale, this firm also do a retail business, and lanterns, slides, &c., may be obtained on hire. Sets for every con- ceivable subject in coloured lithographs are to be found in the lists we have received. These we recom- mend our readers to obtain for themselves.
Stock SLIDE Box.—This has been received from Messrs. Humphries and Co., 268, Upper-street, Islington, who inform us that they have put them on the market at 1s. 9d. each. made, and holds 100 slides in batches of 20 in each division.
JusT as we are going to press we have received an advance copy of Mr. Walter Tyler’s gigantic book, which has upwards of 300 pages. It contains useful information for working lantern apparatus, and prices and particulars of lanterns and slides. This we will review in next issue.

ETHER-OXYGEN SATURATOR. (Vo the Editor.)
Dear Sir, —Your correspondent “ Lux,” Isle of Wight, ! may be assured that his three questions, respecting the use of : may be very satisfactorily ;
the ether-oxygen saturator,
answered in its favour. If he will write me I shall be glad
to give him my experience with it for the last three or four
years (address with Editor). H.R. Sheffield.
Slides thus mounted have ever- ;
It is strongly and neatly ! 1 : “ magic,”
; faithfully,
[ fu the Editor. }
Srr,—In reply to “‘ Lux," I have used the ether-oxygen saturator under every possible condition, and am clearly of opinion :—First, it is not, and cannot be, quite safe ; explo- sions will occur where there are mixed gases and a light, and especially when the pressure is checked at either end of the tube, as in turning down one light for dissolving. A serious accident is almost ‘impossible with the saturator, but the tubes are always liableto be blown off with a loud report, which is quite sufficient to frighten the average audience, and prejudice them against future shows. The saturator is useful for advertising purposes; or class demonstrations, or in the gallery ofa large hall or theatre, where the pops and cracks would not be heard or the smell of ether noticed ; but in a small hall or room, where the lantern is surrounded by the audience, some of whom might tread on the tube or touch the apparatus, it is unsuitable.
Second.—The light is steady and nearly equal to the oxy- hydrogen, but depends upon the jets, the adjustment of the lime and taps, and the skill and experience of the operator.
If “Lux” is bent on using a saturator he should drive
| hydrogen gas through it, and keep the oxyen quite separate
until the gases are mixed in the chamber of the jet; he will then require about 4ft. of hydrogen with rsft of oxygen, and with care be safe from explosion.—-Yours faithfully, C. Goopwin Norton. 38, Marchmont-street, Russell-square, W.C.
[To the Editor, | S1r,—I have used the ether saturator for a single lantern, and it answers well. For two lanterns, it is only a case of dividing and turning the current to 2 different burner; and if it will answer with one burner, it surely will in a second of the same construction. —Yours, &c., SATURATOR. Princes Crescent, Margate.
CHROMO-LITHO SLIDES. | Lo the Editor.}
DEAR Sik,—I enclose a short article which I should like inserted in your very interesting paper for next month—if you deem it of sufficient interest.
I hope to see the Optical Magic Lantern grow more voluminous every month with contributions from an ever- increasing number of subscribers. I think it would be such a capital thing if amateur lanternists were to relate in its colunins their varied experiences connected with that ever- attractive instrument, and which has such capability of application—the optical lantern.
You will notice that I say “optical” lantern instead of I do this because I think it high time that lanternists should speak of the instrument in that way, instead of using the old-fashioned. undignified and childish name of “magic” lantern. It may be that chi/d7ven will continue to speak of it as their parents did in their younger days, as pos- sibly they will think that the old name carries with it a'‘certain charm which is lacking in its moderm and more technical title, but which I think is much more becoming now that it has been ‘‘ evolved" to its present state of perfection.
Wishing your paper every success, I beg to remain, yours
ALBERT TRANTER. GAS BAG EXPLOSIONS. {To the Editor. |
DEAR SIR,—LIave any of your readers ever seen explo- sions of oxygen or hydrogen gas-bags during exhibition, when the chamber of the mixed gas jet has been filled with wire gauze or powdered pumice ?
I do not include attempts to explode the bags by sitting or standing on them, nor explosions with the ether apparatus.

Society Meetings.
CAMERA CLur.—On Thursday, October 3oth, an exhibition of lantern slides was held at the Camera Club, members and friends bringing up over two hundred slides for the occasion. bition was the result, several classes of work being illustrated. Mr. Williams contributed landscape scenes, Mr. White and Mr. Lardeur microscopic sub- jects, Mr. Griffiths some very effective subjects taken in East Anglia; Mr. Howlett pictures, including an excellent view of the Houses of Parliament, and Mr. Chang, hand camera views. Other slides were con-
tributed by Messrs. Laurie, Greene, Sands, and Wel- !
lington. On Thursday, Nov. 6th, Mr. Gale read a paper, entitled “Country Rambles with a Camera." Mr. Frank Howard occupied the chair. There was an excellent attendance, and a very interesting lecture was delivered, illustrated by agreat number of lantern slides. Mr. Gale commenced his address with notes concerning some of his favourite counties, and then
the part of the photographer. The heads of his sub- ject were cottages in landscape, their styles and the material used in their construction, river scenery, country ponds, commons, ploughing, harvesting. The questions of “ Figure in Landscape ” and “ Lighting ” were also discussed and illustrated on the screen, and the lecture throughout was adorned with extracts from In the discussion the Chairman, and Messrs. Hussey, Humphery, Wilkinson, Greene, Davison, and Maskell spoke, and at the conclusion a vote of thanks to the lecturer was carried by acclama- tion. On Nov. 13th, Mr. Bevan gave a description and demonstration of Messrs. Greene, Cross, and

The colour photograph had been printed from a chromatrope and showed the design in fairly bright blue, red, and yellow, with acertain amount of fog throughout. Capt. Abney pointed out that there was nothing new inthe production. He had often ob- tained the same results, and the colours would be found to fade.

Corbould showed and described very effectively |
Hume's cantilever enlarging apparatus. Mr. Bevan fully described and demonstrated the primuline process of printing, illustrating his remarks throughout with many examples. On Thursday, November 2oth, Mr. Pringle gave an address on ‘“‘ Some Old Processes of Making Lantern Slides." Mr. H. M. Elder, M.A., occupied the chair. Previous to the lecture Count Primoli, of Rome, handed round a large and excellent

Previous to the lecture the !
series of instantaneous photographs and other work of his own production. An exceptionally interesting one represented an indoor function with the Pope seated in full ceremony. This had been given ten seconds, detective fashion, but the figures during the time had not moved. Mr. Pringle, in his lecture, com- menced by gainsaying assertions to the effect that lantern slide pictures did not come within the domain ofart. He insisted on a highscale of lighting, clear shadows, and warmth of colour. He sportively sug- gested that the screen pictures could easily be made

by varying his distance from the sheet, and if rough surface was the aim, then all that had to be done was to use a good fuzzy travelling rug as a screen. He then proceeded to give the formulz, working details and distinctive characteristics in connection with several old processes, dry collodion, wet collodion, collodio-albumen, &c., and he illustrated his remarks by exhibiting on the screen comparative slides in the several processes. Some discussion followed, Messrs. England, Wellington, Humphery, Cembrano, and the Chairman taking part therein. . BATH PHOTOGRAPHIC SOCIETY.—The first ordinary meeting after the recess was held at the Royal Literary and Scientific Institution, on 6th November, Mr. W. Pumphrey, president, inthe chair. Mr. F. J. Saunders
| was elected a member of the society, and the election proceeded to urge the necessity for observation on j
of Miss Pearcy and Mr. A. Hinton Jones by committee was confirmed. Mr. Friese Greene read a paper, entitled “ A description of a new machine for printing and illustrating a paper by photography alone, at the rate of fifteen to eighteen thousand an hour.” This ingenious machine was then set working ona spool of coated paper, and the rapidity of its exposing capabilities shown. Another apparatus for rapidly printing the copies was also shown, as well as bands of celluloid negatives and positive paper prints. These were Said to have been produced at the rate of five ex- posures per second of time. Mr. Greene drew atten- tion to an effective spirit lamp for burning given quantities of magnesium powder at brief intervals, and a bijou lamp in which a small wax taper fired the powder as required. During the demonstration a member arranged a camera in the hall and obtained a fair negative of those present. The Chairman thanked Mr. Greene for his paper and the trouble of coming from London to show this machine in public to their society first. He said they were amazed to hear that positives might shortly be obtained therewith from positives. The details of this process, he hoped, would not long be delayed. They were also indebted to Mr. Greene for showing those very compact forms of lamps for the combustion of the metal magnesium. Mr. W. Middleton Ashman enquired of the lecturer the kind of light and the sensitometric value of the films used in producing prints at the rapid rate stated. He also wished to know the ratio of speed the new salt named primuline had to the silver haloids prepared for a high degree of sensitiveness to light. Mr. Greene, in reply, said he used gas light for the bands of prints shown, and the sensitive surface was most rapid. Primuline was much lesssensitive to light, but could be accelerated by an admixture of silver nitrite. The chief advantages he found in being able to produce positives direct from positives. The Chairman mentioned that Mr. C. H. Talbot had presented to the society a copy of the

mehod of photogenie drawing as given by his father, Fox Talbot, before the Royal Society, January 3ist, 1839. Some specimens of Fox Talbot’s early callo- types and photo-glyphtics were laid on the table previous to despatch to the Edinboro’ Society, to whom : they have been presented by Mr. C. H. Talbot, of Lacock Abbey. Mr. Talbot stated that he had made
no alterations to Lacock Abbey, although it appeared
in areport of the society’s proceedings that he had
done so. Messrs. Dugdale and Davis then showed by
means of the oxy-ethyl lime-light apparatus a large
number of transparencies. The first dozen were local
selections made throughout by Mr. H. G. P. Wells.
Scenes visited by the society during the summer ex-
cursions came next from transparencies made by Mr.
Dugdale, the negatives being by various contributing
members. Then followed a number of general subjects,
including views at Lynmouth and other places
adjacent. The light was very brilliant, and reflected
great creditupon Mr. Davis’s manipulation of the
lantern.
BRECHIN PHOTOGRAPHIC ASSOCIATION.—The above association gave a public exhibition of lantern | slides in the City Hall, on Tuesday evening, Nov. 4. In spite of the excitement over the election the hall was crowded in every part. Mr. Shaw Adamson, of Careston, president, occupied the chair. The slides chosen for exhibition were the set entitled, ‘‘ Green- land's Icy Mountains,” taken during a voyage in a | Dundee whaler. Mr. A. R. McLean Murray, High School, read the descriptive lecture, supplemented by | descriptions of his own, in a manner which left nothing | to be desired. The second part of the entertainment consisted of the set “ Round the Farm Yard,” and over one hundred slides contributed by members to a com- : petition which takes place this week. These latter : seemed to take the fancy of the audience, as was evinced by the frequent outbursts of applause, as well ; known scenes and characters flitted in rapid succession on and off the screen. The association’s slides were arranged to represent a tour round Brechin, up one | side ot Glenesk and down the other to Marykirk and : Montrose, Dun, Arbroath, Dundee, St. Andrews, and Edinburgh ; north to Dumblane, Perth, Killiecrankie, Speyside, Cullen, and Aberdeenshire, besides harvest scenes, statuary, and other subjects of varied character. The association’s lantern and apparatus were under j the management of Messrs. Middleton and Stewart, the curator and treasurer of the association, and were manipulated in a most satisfactory manner, no hitch ' of any kind occurring. Admission was by free ticket, with a collection at the door; and we understand the expenses will be quite met by the collection.
HACKNEY PHOTOGRAPHIC SOCIETY.—Theordinary meeting was held on Thursday, 13th November, Dr. : Rolanau Smith presiding. ‘The secretary announced | that ihis was the last day for receiving prints for the | competition, and that Mr. Henry Crouch, the well- ; known manufacturer of lenses, had very kindly promised to give a lens as one of the prizes. There is to be an exhibition of the society's pictures (competi- tion) and lanternslides on December rith next, at St. Andrew's Hall, Well-street. Tickets can be obtained | of any of the members.

LANTERN SOCIETY.—At a. meeting of this society (October 27th) Mr. Louis Fagan gave a lecture on “Wood Engraving.” Speaking of its history, he said it was known in very early times in the East, and was probably first practised by the Chinese. The epoch of its introduction into Europe wasunknown. One of the earliest uses to which it was put was in the manu- facture of playing cards, and there were shown on the screen slides of some remarkable cards which were cut by a French artist. Several slides were then shown of early specimens of wood engraving, amongst them being one of St. Christopher carrying the infant
Four names were put

dated 1483, and a most superb specimen of the cele-
| brated Psalter of Faustus, which was printed from.
blocks on vellum. The lecturer proceeded to explain
‘the method of “ cross-hatching,” showing an example
from the frontispiece of a book published in 1486. Slides of chiaroscuro drawings were next shown. Speaking of Albert Durer, Mr. Fagan observed that he transformed the art of wood engraving, and several very fine specimens of his work were shown on the screen. Two remarkable slides were shown of the frontispiece of the ‘‘ Great Bible” printed by order of Henry VIII. The first of these has on it two coats of arms, one of them being that of Cromwell ; in the second the arms of Cromwell have been removed, leaving a white patch on the picture, he having been charged with treason during the interval between the publishing of the first and second blocks. Mr. Fagan. concluded by showing some beautiful slides of the “Dance of Death.’ On Nov. 3 the annual general. meeting was he!d. After the transaction of business, Mr. J. Hay Taylor exhibited and explained Noake’s: Intermediate Regulator and Chadwick's Eclipse Carrier, which latter was afterwards used for showing the loan collection of slides On Nov. 24 a large. number of members and friends were entertained with fine photographs, which were projected on the screen. Great interest was manifested when the kaleidoscopic and mechanical attachments were brought into use.
: The evening was a great success.

‘ slides were exhibited, consisting of scenery in York- . shire—on the Wharfe, Ure, Swale, and Tees, Bolton, ‘ Rievaulx, and Whitby Abbeys.
The views of scenery further away from home were instantaneous marine pictures from the Isle of Man and other places. The: Lake district was well represented, and the castles of Kenilworth, Raglan, Warwick, Tintern Abbey, and. other similar places had received careful attention by some of the exhibitors, whilst some fine pictures of Continental and Norwegian scenery were exhibited. in a few opening remarks, convinced the assembly the society had made much progress during the year. It had secured a lecture hall, replete with convenience: for experiments and general work, and the public exhibitions of the society had been so successful that.

further efforts of a like character had been invited. Mr. C-H. Bothamley, of the Yorkshire College (vice- president of the society), announced the titles of the various Slides as they appeared on the screen, whilst the lantern was under the charge of Mr. A.A. Pearson and Mr. S. A. Warburton, the hon. secretary of the society. The intervals were filled up by a selection of music performed by the Leeds Private Orchestral So- ciety, Mr. Staniland Hall conducting. The following are the names of the members who showed lantern slides during the evening :—Messrs. Atkinson, God- frey, Bingley, Bothamley, Denison, Denham, Jacob, Pearson, Rodwell, Thornton, Warburton, Wright, Waddington, Whitaker, and Walker. Unfavourable as the weather was, the audience filled the hall, and the proceedings were successful in every sense. PHOTO SOCIETY, DEWSBURY.—Nov. 6th. 1890, Mr. T. G. Beaumont (president) in the chair. The sec. announced that he had arranged with Mr. H. M. Smith to give a demonstration on Dec. 4th. It was pro- posed by Councillor Hepworth, seconded by Mr. C. Naylor, that the society s meetings be held forthwith at the ‘‘ Dewsbury and District Technical School.” the motion was put and carried unanimously. The American set of lantern slides, “In and About
Columbus,” sent by the Boston society, were passed through ‘the lantern, which was worked by Mr.C |
Naylor. Mr. Beaumont gave the descriptive part. The slides were freely criticised as they were placed on the screen. Some of them were greatly admired, others ‘were considered only moderate, and far from being equal to some shown by members at the previous meeting. creditable and
KILBURN, hon. sec. SoUTH LONDON PHOTOGRAPHIC SOCIETY.—On
Friday, November 7, was held the second lantern entertainment of this winter. A lecture was given by Mr. H. G. Banks, the honorary treasurer of the society, entitled, “A Tour to the Channel Islands.” The tour was illustrated by a fine set of coloured photographic slides (many of them Mr. Banks’ own work), thrown ona I6ft. disc by means of the triple that Mr. Banks had built in the early part of the year. During the evening Mrs. Banks and Mr. Norman contributed several songs, and the whole entertainment was much appreciated by members and their friends, who, despite the wretched weather on that night, attended in considerable numbers.

Notes and Queries.
Cornwall.—It is a strange experience; we have made in- quiries, the result of which you will find in this issue. See “ Oil Lamp Matters,” also “‘ Flashes.”
S. D, F. asks : ‘f Do you know of an optical lantern which is lighted by a lamp burning mineral oil with three wicks, which are arranged triangularly, and whether you think there would be any advantage in that form over the ordinary parallel wicks? The ordinary form gives shadows between the wicks on the screen, which it seems to me would not occur with the above arrangement.”’ Ansyver.— All the advantages to be derived from a burner of the form you mention are ob- tained with the circular, or Argand wick.
Neno.—The eyelets may be obtained in two pieces, the
shank of one side sliding through the flange of the other; a'

few taps with a hammer and punch secures them in place. We do not know of an address where they can be obtained, but probably any sailmaker could let you have some.
Slide writes : ‘I am making a mechanical movement for a lantern, and want by pushing ina rod to draw another rod end on towards it. Can you inform me of a simple way todo this?” Reply.—Let the rods be represented by the upper and lower lines, thus Z, the extremities being fastened with a hinge to the connecting line; bore a hole through the centre of connecting piece and pin it down.
Mr. Wm. Stocks (of Rye) writes: “ With reference to your article on ‘Large Object Glasses’ in November Journal, I have tried Dalumeyer’s 23 portrait combination, and I cannot find that any brighter picture can be shown on the screen than with 13in. front and 2in. back combinations. The latter is, I think, the largest size Dallmeyer quotes for lantern use.”
C. 8. Scott asks for the address of any maker in this country of incandescent electric lanterns. Answer.—We think you could have one constructed by Newton, 3, Fleet-street ; or Steward, 406, Strand, both of London.
J. H, R.—Have inserted.
Hf, P. C—(t) If the lightning will not appear on the screen under the conditions mentioned, the colouring of the forks is apparently too dense for the light you employ. (2) If you procure the issue of this journal for last May, with : index, you will find articles on the subjects you require. No.
1 is quite out of print, No. 2 is sixpence, and all the other numbers up to date are three-halfpence, post free. | Mento,—(1) Write to Mawson and Swan for their booklet, : “ How to Make Transparencies.” (2) Free.
W.—If the screen is at all transparent, the more folds there are at the joins the more apparent will be the line.
W, D. asks: “ (1) In the January number of the journal, under the heading ‘Opaque Lantern,’ you mention an American Wonder camera; could you tell me the probable ‘cost, and where obtainable? (2) What is the best angle in
: making a single or double form of lantern (I presume the j angle would be the same in both)? (3) Would the object glass of the same lantern you use for illuminating work satis- factorily?” eply.—(1) Write to E. B. Foote, jun., 120, Lexington-avenue. New York, U.S.A. (2) We do not understand your meaning 7e the angle of lanterns. (3) If you have reference to the Wonder camera, the same lens will answer.
7.—The chamber or magazine in the Grifin hand camera is secured to a traveller, which has bearings both at the back and at the side. We have tried it, and the motion is perfect.
B.—The eighteenpenny clip is vastly superior to the shilling one.
Venthal.—Yes ; the apparatus you mention is very gvod.
Ina Pic.—Itis evident that you had far too much hydro- ‘ gen turned on; why not try the method you suggest, it will | only take a few minutes ?
Negative.—The 4-plate negative is greatly over-exposed, but the }-plate one is about right.
H, M. Hedley.—Thanks ; but regret it came too late for this issue.
Duffer.—In our next. We appreciate your kindness.

. Rayapuram Madras, 27th July, 1889. Dear Sirs,—Mr. F. York was kind enough to send me a sample dozen of your Lantern Plates for trial, and [have much pleasure in stating that in my opinion they are the most perfect Plates of their kind.
I do not think you exaggerate in the least in saying that Collodio-Bromide is superseded, for when one can get such perfect Plates for 1s. a dozen, no one would think of going to tae trouble of making Collodion Emulsion with its uncertainty and worry.
I spoilt the first of the dozen purposely by giving different exposures on the two halves of the Plate to ascertain their rapidity, but after that I got eleven very beautiful transparencies with the remainder of the dozen, and since that I have used many dozens of your plates with the most gratifying success. I have had some thirty dozen out, and find they keep exceedingly well in this climate, for I used some that had been in a cardboard box some four months and they were perfect as at first. Yours faithfully,
